/**
 * 核心原理
 * 1）@EnableRedisHttpSession导入RedisHttpSessionConfiguration配置
 *    1 给容器中添加了一个组件
 *      SessonReppository >>> RedisOperationSessionRepository,redis操作session的增删改查
 *    2 SessionRepositoryFilter >> Filter: session存储过滤器，每个请求过来都必须经过filter
 *      1.创建的时候，就自动从容器中获取到了SessionRepository;
 *      2.原始的request，response都被包装了。SessionRepositoryRequestWrapper,SessionRepositoryWrapper;
 *      3.以后获取session。request.getSession();
 *      4.wrapperRequest.getSession();===>SessionRepository中获取到的。
